COVID-19 was declared a world-wide pandemic in 2020, consequently affecting societies all around the globe. This thesis investigates one of these effects, namely how the pandemic affected occupant loads in office buildings and its subsequent effect on fire evacuation. Occupant load is one of many important factors when designing a building in regard to its fire safety, as it is a key component in
The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. Kombucha is produced through fermentation of sweetened tea by a complex community of bacteria, mainly dominated by acetic acid bacteria, and a variety of yeast. D
Purpose: This study attempts to makes sense of airport consumers' mind states during their shopping, and their influence towards the following airport shopping experiences. Methodology: Firstly, semi-structured interviews were adopted for the purpose of gaining deep and rich knowledge about the shopping mentalities of passengers as airport consumers, which offers comprehensions and interpreta
Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. To gain a better understanding of the Arctic carbon cycle in the future, global dynamic vegeta
The difference between the academic legal research and the real-world ap-plication is probably of no larger difference anywhere else than in the sphere of International Humanitarian Law. This thesis aims to research this discrepancy, and explore how the environ-ments and frictions of the modern battlefield effects the application of the many laws and rules of IHL. Through analyzing the most key p
Skin ages as a result of the failure of several mechanisms that are triggered by both internal and external factors. The accumulation of damaged proteins is an effect that comes with age due to the dysfunction of the proteasomes and their decline in activity, which leads to dull looking skin. In addition, as we age the effects seen on are skin includes the formation of age spots as well as hyperpi
Abstract Background Swedish foods have difficulty competing against imported food that has different cost scenarios. Food price inflation has today led to a major focus on low cost for consumers. This focus has created a risk of lower food quality for consumers and lower profitability for the food industry. Target To develop a principled business model with a focus on identifying realizable value
In this master´s dissertation I investigated if it is possible to increase the total stability for excavations in clay, if suction is taken into account during the calculations. The work has been performed at, and in cooperation with, Sweco Civil AB as well as the Dept. of Construction Sciences at Faculty of Engineering LTH, Lund University. The objective of this master´s dissertation is to asse
This study focus on the gelation process of 1-methylidene ethane-1,2-dicarboxylic acid (MIA) polyesters and what causes the gelation. The influence of oxygen during the syntheses, how the molecular weight is affected and how the polyester changes chemically was studied. Analytical methods used were SEC, titration and NMR. The replicability of the experiments was investigated and confirmed. Testing
This study examines the impact of sky-bridges, as an egress component, on total evacuation of a high-rise building by using an evacuation model named Pathfinder. Five scenarios, with different combination of aspects such as height of the building, number of sky-bridges (and the subsequent inter-distance between them), and people allocation have been simulated. The comparison between the results fr
This thesis investigates the possibilities for setups measuring how the surface structure of nanowires (NWs) influences their electric properties. For this the abilities to clean surfaces and detect nanowires (NWs) are examined, and an attempt to build a setup is made. Compared to the size of NWs and surface area measured in scanning tunneling microscopy (STM), an “infinite” surface of GaAs/AlGaAs
Collective collapse occurs when a majority of the players in a team suddenly perform below expected level in a match, in spite of a satisfactory start, or when a team underperforms right from the start. Research results from a study on 146 male players and 15 coaches in various team sports at the elite level, and a study on a team involved in a collective collapse, and the opposite, a winning turn
Family doctors and general practitioners (GPs) are the frontline in the management of fatty liver disease. With its high prevalence and strong association with other conditions commonly treated in primary care, the voice of family doctors and GPs has an important role in informing the discussion on the redefinition of fatty liver disease. Primary care uptake of any proposed name will be hampered i
This paper analyses John Buridan’s approach to the notion of syllogism by putting it in the institutional and doctrinal contexts where he belongs, that is, the faculty of arts of the University of Paris and its Aristotelian logical tradition. The analysis aims to ascertain Buridan’s innovative contribution to the history of logic by underscoring the points of continuation and rupture with respect
The life of cutting tool inserts is critically important for efficient machining, reducing manufacturing cost, embedded energy, and enabling more complex parts to be machined. For these applications, cemented carbide (WC-Co) materials are a prime candidate. The performance of these materials can be limited by early fracture, typically via an intergranular fracture path with respect to carbide grai
Mobile BI (m-BI) is an extension of BI delivered on mobile devices such as smartphones and tablets. Even though proponents of m-BI are highlighting its capabilities and outcomes, still its value-generating potential in organizations is surrounded by ambiguity. Given this uncertainty, we use an affordance approach to explore the action possibilities and benefits arising from the interaction of m-BI
High levels of stress have been documented to impact memory and attention. On the other hand according to previous literature low levels of stress can be helpful in preparing individuals physically and mentally to become active. Relaxation techniques have been proved to reduce stress successfully but there is debate regarding if they have the same positive effects on cognitive performance as well.
